I was 17 when i was diagonesd with high blood pressure, i was eating a lot of salty food, i stopped it and my blood pressure was fine, I've been off and on blood pressure medication, but for the last 4 years i have had untreated high blood pressure and i was really over weight, i went to my doctors and i bend down when i got back up my heart rate was 188 they did an EKG and my rate had already gone back down to 112, he told me to go to the ER right way, i went and they did ct scan of the brain, nuclear medicine test since im allergic to the iodine, x-rays of the chest and a echocargiogram, everything came back negative, they gave me cardizem 60 mg every 8 hours to stable my heart rate, i am on a heart ekg monitor for a month, i am not a smoker or a drinker my cholestral is perfect and my sugar, my question is can i possibly have an arota dissection or anyruesym due to the blood pressure i had it 150/110 when it was untreated. ive lost 33 pounds, ive had 2 echocardiograms and both came back normal, ive had this pressure in my head for 2 months dont know if its from anxiety or due to lack of oxygen to the brain, also ive had excessive yawning, im terrified that it could be a dissection, can echocardiograms rule out a dissection anywhere in the body ? also my blood pressure is at 120/74 now.
